Hi,

I dislike solution number 1 too :)

But clearing the cache in add_job is not enough :/ Other functions can
alter the cached data: when a user is renamed, when a group changes
its group type or its name, when a job is removed, when a user is
deleted, etc.

I liked the idea from http://www.danga.com/memcached/ where the cache
was always accurate (using getter+setter). I don't know how applicable
this is for Savane.
